[GFS2] Further updates to dir and logging code
This reduces the size of the directory code by about 3k and gets readdir() to use the functions which were introduced in the previous directory code update. Two memory allocations are merged into one. Eliminates zeroing of some buffers which were never used before they were initialised by other data. There is still scope for further improvement in the directory code. On the logging side, a hand created mutex has been replaced by a standard Linux mutex in the log allocation code.
